GM RWD mid-size and large Vans/SUV's (Jimmy, Bravada, TrailBlazer, Yukon, etc..) with an electronic 4sp automatic use the 4L60. The 4L60 has a known weakness with the Sun Gear Shell. It will take out 2nd, 4th and Reverse. This has been a known problem for years. It is not uncommom for the Sun Gear shell to crack at 70-80,000 miles. GM historically has not addressed this issue so if you use a GM part in the rebuild you may end up with the same issue. Do a Google search on "sun gear shell" and "4L60" and you'll see what I mean. If replacing the part use an aftermarket part that has addressed this issue. If you have this fixed at the GM dealer they will charge you $800, will only replace the Sun Gear shell, and it will happen again. If you must have a dealer do it beg them it use an alternative part.
For those you have a stock sun gear shell in your 4L60 simply don't floor it from a dead stop and avoid full throttle 4-2 downshifts. I have 215,000 miles on the 4L60 in my '96 Astro Van and after learning of this issue several years ago I simply take it easy. The 4L60 in general is a good trans and is an electronic version of the 700-4R used in the mid 80's up thru 1993. Since they were also used in the Vette's and Camaro's the aftermarket has many parts to significantly beef-up these transmissions in high horsepower applications.
I had a problem on my 99. It wouldn't engage in reverse. Turns out there was a Gear Hub that fractured. I had to have it rebuilt.
Does anyone know of any chevy beretta cam shaft problems?
3.00 to 20.00 dollors but some times it just a loose bolt
the automatic transmissions are hit or miss. most of them have problems eventually. The door Handles are known to brake.
No..... But they can have problems just like any other trans.
It depends on what engine you have.
Yes a lot of 2000 and 2001 windstars came with junk transmissions from the factory. Most of them blew after 5000 miles.
yes
We have a 2001...same deal. Switch is 65 and the plug is 72 dollars...Plastics throughout the car are cheap. Electrical is not well thought out. Great engine but No more chevy's for this family.
silicone spray helps wipe it on all rubber gaskets and wherever the gasket touches metal
The company that produces the Astro Van is a well known company called Chevrolet. The Astro Van by Chevrolet was first produced in the 1980s, and was quite popular.
The intake gaskets are none to leak antifreeze. It is a real common problem with the vortec engines. Other then that there goods engines and have really no other problems.
Astro, Pluto, and Lassie were all fictional dogs. Astro on the Jetsons ( he talks), Pluto a Disney character, and Lassie should be well-known to all as a live character, not a cartoon. woof woof.
